understood;.hovever, thatr. so fait as the locationofftlie lamp and itsmountingis concerned, such` locationi may be. otherwise selected.'L This location, however,w is. convenient to thedi'iver. Y Y

The section ofA tlie door' frame 10'. is shoWn'iii Figures 2.and`5. The activefelef men-ts of, the lamp itself' are exterior to the support 10,.,While the, means` for actuatingA the movable' parts ofthelamp so asto Variously directf its rays are*l located Within the l car bodyand just inside the" support on Wallmember 10.`

The mounting. for the 'lampyas hereinv shown,` ismade asviollowsz. K p

14 designates ahorizontal tube memberwhich extendsthrough and is-adapte'df to rota'tively, itatits innerfend.- ina bearing inther frameaorsupporti 10. n The tube ter#- minatesl a shortdistance inside the support 12.0:7 and a Weatherproof j oint can i be'l formed. aroundf theY tube at its inner end'by meansoitea preferably frictionl Was-her l5 that'is-l axially? pierced to rec'eivethe tubeY andis seated flat against the t inner side of the support 10l and can be pressed against the flat, inner face of said support by bracketmember 16, forming a clampingplate which is axially and nonrotatively seated in a groove 17 n of said tube. In. practice the innerend of the tube is reduced in diameter and the opening of the bracketmember16 Y,

tends a distance outwardly beyond the tube to constitute' a lamp operating terminal 21. It also extends inwardly beyond the tube and inside the car body and thereat has a flattened formation 22, as herein shown, on

which is mounted a switchi 23 hereinafter to be more particularly referred to. The shaft 2O is hollow7 to afford a conduit or passage '24 for the lamp conductor cord 25, one branch c of which is adapted `for con-` nection to a battery or other source of ourrent supply, and the other branch c1 of which is dividedand includesswitch con* tacts o2, 03 that areadapted to be bridged by a suitable switch c4, the mounting of which is designated as a whole by 23; the conductor c5 beyond the contacts going back to the battery or other source of current supply.

The outer end of the tube 14 is externally threaded at 28 to engage an internally threaded sleeve nut 29, whose function is to directly support the lamp structure in the arrangement herein shown, and asv hereinafter will be described. Asherein shown, the tube 14 extendsk through a cone-like block 31 fitted against the outer face of the support or wall member 10 around the bearing therein through which the tube emerges. This block is fastened to said support or wall member 19 by means of screws 81. A water proof joint can be made between the outer smaller end of the block and tube 14 t by a nut 32 threaded to the tube 14, a lock nut 33 bearing thereagainst-and a compres# sible packing'34 between the nut 32 and the bottom of a recess 35 inthe smaller end of said block which receives said nuts and packing. Y' The clamping action and reaction of said `nuts has the effect to press the fric-` tion washer 15 and the compressible packing against their seats on `thelwall member and block, respectively.` The use of the block 31 avoids 'the necessity of marring the wall member or door frame to adapt "the structure, when employed in con-nection with the wall member of a closed car body.

The outer end of the threaded sleeve nut constitutes a direct support f or the lamp structure which is designated asa whole by 36. The sleeve nut 29 is locked on the tube 14 by anut 29 threaded tothe tube 14 and backed by a lockk nut 29-".The connection.V

piercing the bracket Sfto pass thereover,

' and thereafter upsetting the end ofthe sleeve nut to constitute a holding shoulder 40 which non-rotatively fixes the lamp structure to said nut. The bore of the outer end of the vsleeve nut is reduced to form a bearing for the tubular shaft 2O closely adjacent to the swivel connection of the tubular shaft20 to the block `54.

Referring to Figure 6, it will be noted that the neck portion ofthe reel casing has an` externally threaded terminal41` fitted over by an internally threaded and eXteri-' neck is provided with a downturned vend Y that has an external cone formation 48 which lits an internal seat 49 that is formed Yinv the `upstanding terminal 41. The said coneelike parts are forced together by en gagement of the shoulder 43on the nut 42 against an upwardly facing annular shoulder 51 on the neck portion 46. The. engagement of the tapered portions is such that the nut 42 will lock the tapered parts from relative turning due to vibration, but will permit them to relatively turn when a permissible manual force is applied tothe lamp. Such `manual force isapplied to the lamp through the horizontal portion of the neck 46 by the following means: i i f To the terminal 21 of the tubular shaft20 is fined, as by meansof a set screw 53, block 54. Said block isprovided at` its upper edge with `a slot `55 `downwardly into which projects a lug 56 that is finedto and depends fromthe horizont-alportion of the said Vblock and the lamp `supporting neck 46 afforded by the slot 55 and lug 56, the said lamp casing will-I be swungv or rocked about the axis of the downturned end of the neck 46, as permitted by the sufficiently loose fitv '2O is controlled from the driver-s station inside the car body by means made as follows:

That portion of the shaft QOwhich liesinside the car body is flattened to produce the inner terminal 22 abovereferred to, and said-flattened portion carries at its innerv end and on both sides anti-friction rollers 58 which travel in a track 59 of a hand' lever GO that is pivoted by a pivot pin 6l to the bracket arms 18 of the frame member 16 before referred to. rllhe track portion 59 referred to is formed by making the hand lever 60 hollow andv giving it a formation that produces between its pivot and manually directed endl a rather sharp angle portion 63.' The inner side ofthe hand actuated cam leverV is slotted or open atv 64,'as

shown in Figures 2 and S, to permit the in-` ner terminal 22 of the shaft 20 to pass therethrough; andthe anti-friction rollers 58, which are rotativelyk mounted on' the end of the flattened terminal are placed within the hollow or channel shaped' hand leverthrough one off its openends during the assembling operation lViththis construction it will be noted that when. the lower end of the hand leveris pulled inwardly` or away from the support 10, it serves to move the shaft 20 towards the closed cir body, andzthrough the swivel connection, due to the slotted block 54 and the lug 56, the lamp casing willibe swung in a horizontal plane inwardly towards the car, as shown in. Figure 4. l/Vhen the hand lever is swung in the other direction,vthe oppositeadjustment of the lamp casing and itsk lamp will be etfected, as will be clear from an inspection of Figure 3. In Figure 4, it can be assumed that the parts are in position to effect) the greatest throw of adjustment of the lamp casing away from the closed car body. In Figure 5 the adjustment corresponds to that shown in Figure 1wherein the lamp casingis adjusted directly forward. Figure S indicates innermost adjustment of the lamp structure.

The lamp structure may be adjusted in a vertical'plane byy turning the tubular support 14, which may be effected by grasping the lever 60 and" bracket 16 in much the same manner as grasping a door' knob, and turning it either forwardly or rearwardly, and thereby effect angular adjustments'of the lamp structure inavertic'alfplane With these two positive adjustments', itA will be observed that numerous combina-l tions thereofL will ef'ectra substantially universal adjustment of the lamp structure' about the axis of the nut 42 and the axis` ofthe shaft 20, so that light may be projected' from the lamp in all directions and'. by means which are readily accessible 1nsidea closed car body.

lt willbe understood that the structural details illustrated may be varied'within the spirit and scope'of the claims 'hereto Aappendedsand that the invention is notlin'iit-ed to the details of construction shown, except'y as to vclaims wherein the details are specifically set forth, and as imposed by the prior art.
